To all whom it may concern:

Be itknown that I5, Answer A. Rus rne BERG, a citizen of the United States, anda resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Generators and: Burners; and I do hereby declare that the following, is a full, clear, and exactdescription of the same, reference being had to the. accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention pertains-to a fuel gas generator and burner adaptedifor use in connection with stoves or furnaces'and where in a plurality of starting burners are formed on the top of a generating burner and below an oil supply generating pipe and a car-bursting pipe to initially heatthe oil supply pipe to vaporize the oil therein, which vaporized oil is mixed with air in the carbureting pipe to form a fuel'oil-gas to 1 e burned to heat an annealing furnace. The process of oil-gas generation, after being started by the starting burners, is carried on by the generating burner which also burns the oil gas already generated.

It is an object ofthis invention to construct a fuel gas generator and burner wherein the vaporizing and'the carbureting pipes are adapted'to be heatedsimultaneously by either the starting, burners or the generating burners.

Another object of the invention is the construction of a generator and burner having the starting and the generating burners positioned below the control valve and the vaporizingand mixing pipes.

It is also anobject of this invention to provide a generator and burner wherein an annealing furnace is adapted to be heated'by a valve controlled burner receiving-a fuel.'

gas from a carburetor which is heated by burner flames which also act to vaporize oil in agenerating'pipe before the vaporized oil is admitted into the carburetor where air is carbureted with said vaporized oil to form the fuel gas.

It is a further object ofthis invention to construct a generator and burner wherein oil vaporizing and mixing mechanisms are simultaneously heated by the same burners.

It is furthermore an object of the invention to construct a generator and burner having aacarbureter provided with a valve at each end thereof for controlling: the admittance and the discharge of gas therefrom.

It'is an-important object of this invention to construct agenerator-and burner having the carbureter mounted above the 011 vaporizer to permit fueloil-gas mixed therein toube fed downwardly to a generating burne and to aheating burner.

Other and i further. important. objects of the invention will be; apparent from the disclosures-in the drawings and specificat1on.

The invention (in ,a preferred) form) is illustratcdrin the drawings and hereinafter more fully described.-

As shown onthe drawings.

The reference numeral 1, indicates an annealing arch or furnace, lined with firebriclrs or fire-stones 2, which form the inner wall of? the furnace. Formedin the upper central portion -ofthe furnace is a. heating burner passage 3, into which projects the lower endof a burner jet, pipeor tube 4, the upper projecting. end of which is eX- ternally threaded and engaged 111 an internally threaded arm or collar 5, integrally formed on the lower part of a valve casing 6. Adjustably or slidably' disposedwithin the valve casing 6, is'a 'valvehead or p15- ton 7, to which one end of a valve stem or rod '8, is attached. The valve stem 8, projects longitudinally through the valve caring 6, and outwardly through a longitudinally passaged externally threaded sleeve 9, integrally formed on one end of said casing. Disposed against the outer end of the sleeve 9, is a packing 10, which surrounds the valve stem and is held in position by means of a washer 11, and a cap 12, which is removably threaded upon said sleeve with the valve stem projecting through the closed apertured end thereof. The outer end of the valve stem 8, is squared as denoted by the reference numeral 13, to receive a handle or tool to permit actuation of the valve stem and the valve head attached thereto. Threaded into the open end of the valve casing 6, is one end of a sleeve coupler, union or nipple l t, the end of which affords a stop or a valve seat for the valve head 7.

Threaded n 3011 the other end of the union 14, is one end of a Y-pipe fitting comprising a main pipe section 15, and a downwardly inclined pipe arm 16, integral therewith. Alined with the pipe section 15, and the Valve casing 6, is a carbureting or mixing tube or pipe 17, one end of which is threaded into the other end of the pipe section 15, while the other or air intake end is open.

Rigidly mounted upon one side of the furnace 1, is a bracket or support 18, upon the horizontal top of which is secured a long hollow casting 19, whose interior forms a gas chamber and having an inclined end wall 20, at its inner end provided with an inlet opening 21. As clearly shown in Figs. 5 and 8, the top of the gas chamber casting 19, is formed to provide two parallel generating burners 22, separated by a middle starting burner trough 23, in which a wick 24:, is placed. Formed to the outside of each of the generating burners 22, is an outside starting burner trough 25, having a wick 26, disposed therein. Closing the inner ends of the starting burner troughs is a low transverse supporting wall 27, integrally formed on the casting near the inner end thereof. Tntegrally formed transversely on the top of the outer end of the casting 19, is an apertured supporting wall 28. Threaded into the opening 21, of the casting is the lower end of a sleeve coupler or union 29, the upper end of which is threaded into the pipe arm 16. The wicks 24 and 26, of the middle and side starting burners are adapted to be saturated with kerosene or any other suitable hydro-carbon to permit the wicks to be lighted for starting the operation of the device.

A curved, looped or U-shaped oil supply, vaporizing or generating pipe, is disposed above the generating burners 22, and the starting burners 23 and 25. Said generat ing pipe embraces a curved yoke or elbow 30, which rests upon the top of the supporting wall 27, below the inner end of the carbureting tube 17. Secured in one end of the elbow 30, is the inner end of a long pipe arm 31, which is disposed directly over one of the generating burners 22, and has its other end projecting through an opening for the purpose in the supporting wall 28. Engaged in the other end of the elbow 30, is a shorter pipe arm 32, which is longitudinally disposed directly above the other generat ing burner 22, with its outer end terminat ing to the inside of the supporting wall 28, and a little beyond the outer intake end of the carbureting tube 17 The generating pipe is positioned directly above the casting 19, with the pipe arms 31 and 32, parallel to and above the generating burners 22, and between the middle starting burner 23, and the respective side starting burners 25, so that the flames from said burners may strike and heat the same. Connected to the outer projecting end of the vaporizing arm 31, by means of an elbow fitting 33, is an oil feed pipe 3 1, which is provided with a regulating valve mechanism 35.

Attached upon the outer end of the vaporizing arm 32, t0 the inside of the supporting wall 28, is an oil vapor control valve mechanism comprising an upwardly directed arm or pipe 36, the lower end of which is curved to permit the same to be threaded upon the arm 32. The upper end of the pipe arm 36, is open and is internally threaded to removably receive a plug 37, to permit cleaning of the interior of the valve when the plug is removed. Integrally formed at right angles across the upper portion of the pipe arm 36, and communicating with the interior thereof is a valve casing or sleeve 38, which is alined with the carbureter 17, and has the outlet end thereof disposed directly opposite orin front of the open air intake end of the carbureter. Bemovably threaded into the outlet end of the valve casing 38, is a valve plug 39, provided with a tapered vapor gas outlet opening, Adjustably seated in the valve outlet opening is the tapered valve end or needle point l0, of a valve stem or rod 41, which projects longitudinally through the valve casing 38, and has the outer end thereof squared as denoted by the reference numeral 42, to receive a tool or handle to permit rotation of the valve stem to open or close the valve outlet opening. Tntegrally formed on the valve stem 11, intermediate the ends thereof is a threaded shank 43, which is adapted to thread through an externally and internally threaded sleeve nipple 44, provided with an integral nut collar 45, intermediate the ends thereof adapted to contact the other end of the valve casing 38, to close the same. The outer end of the nipple 4:4, is ground to receive a packing L6, thereagainst. The packing as, surrounds the valve stem tl, and: is securely held in position by means of a washer 417, and a cap a8, which is threaded upon the outer end of the nipple. The closed end of: the cap. 48, is centrally apertured to permit the valve stem to project therethrough.

The operation is asfollo'ws:

To start the generator and burner the wicks 24 and 26, of. the middle and side starting burners are first saturated with kerosene or any other suitable hydro-carbon, and then lighted. The heat from the resulting flames acts to rapidly heat the vaporizing arms 31 and 32, and also the carbureter 17, which is positioned above said starting burners and said vaporizing arms. By opening the valve 35, kerosene .or any other suitable hydro-carbon is supplied to the caporizing arm 31, passing around through the yoke 30, and into the vaporizing arm 32. The heat from the burning starting burners 23 and 25, heats the arms 31 and' 32, .thus causing the oil Within said arms to be vaporizedto form an oil vapor.

The controlling valve stem 41, is rotated byapplying a tool on the squared end 42, thereof, thereby causing the threadedshank 1-3, to move outwardl through the nipple 14, simultaneously Withdrawing the valve point 40, out of the valve outlet openingin the plug 39. The oil vapor is thus permitted to flow from the arm 32, through the valve pipe 36, and escape through the open valve outlet. The air is thoroughly mixed with the oil vapor during their passage through the carbureter, thus producing or generating an oil-gas fuel.

In starting the apparatus oil-gas fuel produced by mixing air With the heated oil vapor in the carbureter, flows through the Y fitting 1516, into the gas chamber in casting 19 and escapes through the burner-openings of the generating burners 22, and is lighted. The resulting flames from the burning generating burners pass upwardly around the vaporizing arms 31 and 32, to heat the same'and the carbureterl'flwhich is dis posed thereabo ve, thereby continuing to vaporize the oil in the looped generator, or vaporizer 30-32. The process of oil-gas fuel generation is thus perpetuated, and the starting burners, ofcourse go out after the oil with which the Wicks 24 and 26 were saturated has burned up.

After the generator and burner has been set into operation to produce a continuous supply of oil-gas fuel, as described, the annealing furnace 1, is heated by pulling outwardly on the furnace burner valve stem "8, thereby moving the valve head 7, and opening the furnace burner valve to permit oil-gas fuel from the pipe section 15, to flow through the union 14, and the valve casing-6, into the burner-jet 1, and out of the burneropening 3. The escaping oilgas fuel from the burner opening 3, is lighted from the interior of the furnace and the resulting flame heats the interior of the furnace.

Vith the parts arranged as described, it willbe noted that all of the starting burners and the two generating burners when operating act to heat not only the vaporizer 3032, but also serve to heat the earbureter 17, thereby acting to keep the vaporized oil heated before and after it enters the earbureter where the heated oil vapor is mixed with air to form the oil-gas fuel.

When it is desired to shut off the genera tor and burner the oil supply control valve 35, is firstclosed to discontinue the oil supply to the vaporizer. The generating burners 22, are then allowed to burn until the oilgas fuel supply is used up. The oil vapor valve and the furnace burner valve may be closed when desired or adjusted to effect any desired opening thereof, by operating the respective valve stems. The generator and burner parts are removably connected to one another, and are further provided with removable plugs to permit cleaning of any of the generator and burner parts when necessary.
